SPECIFICATION forming part of Letters Patent No. 373,185, dated November J 5, 1887.

Application mea May 13,1887. serial No. 238,054. (No model.)

To aZZ whom it may concern:

Be it known that I, GEORGE FRANKLIN HIG- GINS, ofv Chicago, in the county of Cool; and

. and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had tothe accompanying drawings, which form part of this specification. Y

My invention relates to an improvement in car-heaters; and it consists in a heater de signed for use in cars, and which is tov be heated by gas, and which is provided with air-chambers, into which fresh air is taken, heated, and then discharged into the registerbox, as will be more fully described herein` after.

The object of my invention is to produce a heater for cars in which gas is burned for the purpose of heating the air which is introduced into the car, and to produce a substitute4 for the ordinary stoves which are the source of so much danger in case of an accident to the cars.

Figure 1 represents a vertical cross-section of a heater embodying my invention. Fig. 2v vis a vertical section taken at right angles to duction of the pipe which conducts the gas 5o to opposite sides of the hot-air chamber F.'

which is t0 be burned. At asuitable distance in the rear of the burner is placed a partition, C, which rises to any suitable height in the combustion-chamber, and prevents the products of combustion from escaping too freely through the pipe D, which leads from the rear end of the combustion-chamber. This pipe D projects upward at a suitable angle, and then passes horizontally through the bottom of the register-box E, and thence up through the top of the car. Placed in the top of the combustion-chamber is the hot-air chamber F, intol which fresh air is conducted byV means of the two pipes G, which pass up through the bottom of the car and through the combustionchamber, and have their upper ends connected The cover H for the mouth of the hot-air chamber is provided with a vertical iiange or par- I tition, I, which extends any suitable distance inward into the chamber, for the purpose of preventing the two currents of air from the pipes G from mingling together when they first enter the chamber. After the two currents of air introduced by the pipes G into the hotvair chamber F have once started backward, they will continue to move toward the register-box, and thus are prevented from interfering with each other in any manner, or from entering one pipe and passing down into the other. The air in the hot-air chamber F is discharged directly into the box E and rises upward into the car.

The irechamber A does not extend entirely across the inclosing frame or case J, and thus there is left a space or air-chamber, L, upon each side thereof. These two chambers L are separated from each other by means of a vertical partition, N, which extends along the top of the tire-chamber A and reaches up to the top of the inclosing-frame. To prevent the currents of air, which are introduced into the front ends of these chambers L through the pipes O, which passup through the car, from passing too rapidly through the chambers, there are placed in the chambers the inclined partitions P, which serve to deflect the rising currents of air upward toward the top of the frame, and thus compel them to pass along over the top 'of the hot-air chamber in its passage toward the openings V, through which the air escapes into the register-box.v The air which is introduced into these side chambers, L, is brought in contact with opposite sides of the fire-box, and hence is heated as it rises to the top of the inclosing-frame. In the bottom of the register-chamber is placed a false bottom, so as to lcover the top of the pipe'D, which passes through it.

The lower ends of the pipes extend through the bottom of the car, and are provided with vertical partitions Q, which extend any suitable distance upward in them, and with the bottom pieces, R, to which the lower ends of the partitions are fastened. The ends of the pipes are cut away upon opposite sides, so as to form an air-opening upon each side of each partition, and thus` insure a current f air passing upward into the pipe no matter in IIOO the cover H, provided Witha partition for separating the currents of air and located at the junction of the pipes leading to the inner hot-air chamber, substantially as shown.

2. The combination of the fire-chamber, the hot-air chamber, located in the fire-chamber and provided with an opening for the escape of the hot air, the pipes which extend up through the bottom of the car and introduce fresh air into the hot-air chamber, and the side chambers, L, arranged on opposite sides of the fire-chamber and provided With openings for the escape of the hot air, and having the inclined partitions and a vertical partition, N, which separates the two chambers, substantially as described.

3. Aoarheater composed of the combustionchamber provided with a vertical partition, the hot-air chamber placed in the top of' the combustion-chamber, the pipes which introduce fresh air into this chamber, the Side chambers, the vertical partition which separates the side chambers, the inclined partitions placed in the side chambers, and the registerbox, substantially yas set forth.

In testimony whereof I aix my signature in presence of two witnesses.

GEORGE FRANKLIN HIGGINS.
